settingsDelHostOverride returns "not found" - UUID not passed in URL path

[yannickgranger]

Bug Description

The unbound_manage tool's settingsDelHostOverride method returns {"result":"not found"} even when the UUID exists and is valid.

Root Cause

The MCP server appears to pass the UUID as a JSON body parameter instead of in the URL path. The OPNsense API expects:

POST /api/unbound/settings/delHostOverride/{uuid}

But the MCP server seems to be calling:
POST /api/unbound/settings/delHostOverride
Body: { "uuid": "..." }

Steps to Reproduce

1. Create a host override using settingsAddHostOverride
2. Verify it exists via settingsGet (UUID visible in response)
3. Try to delete using settingsDelHostOverride with params: { uuid: "..." }
4. Returns {"result":"not found"}

Workaround

Direct curl call with UUID in path works:

curl -k -X POST "https://opnsense/api/unbound/settings/delHostOverride/{uuid}"

Environment

- opnsense-mcp-server: v0.6.0
- OPNsense: 25.x

Affected Methods

Likely affects all settingsDel* methods that require UUID in URL path.

Fixed by PR #11 — uuid now passed in the URL path for del/get host-override (and the firewall GetRule path), so settingsDelHostOverride resolves the UUID correctly.
